To all whom t muy concern.-

Be it known that I, WILLIAM F. DUNCKER, a citizen of the United States, and a resident of Wrightsville, in the county of York and State of Pennsylvania, have made certain new and useful Improvements in Intestine- Oleaners, of whichthe following is a specification.

M y invention consists in an improvement in machines for cleaning intestines of hogs, beef, and sheep for casing of sausage, ctc.; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a vertical longitudinal section, and Fig. 2 a top plan view, of a machine 'embodying my invention. Fig. 3 is a side elevation thereof. Fig. 4 is a cross-section on about line 4 4 of Fig. 1.

Fig. 5 is a detail sectional plan viewlof they device for turning the casings. Fig. 6 is a detail vertical section on about line 6 6 of Fig. 5. Fig. 7 is a detail perspective view of one of the Scrapers. Fig. 8 is a detail perspective view of the revolving feeder for the casing-turner, and Fig. 9 is a cross-section on about line '9 9 of Fig. 1 g and Fig. 10 is a detail perspective view of the presser.

In constructing the machine I employ a suitable framing, which may comprise side plates A A', as shown in Figs. 1, 2, 3, 4, and 9. In suitable bearings in the framing I journal the feed-rollers B B near one end of the machine, and the bearings of the roller B may be adjustable by means of a screw B2, (see Figs. 1 and 4,) so the rollers may be caused to press upon the casings with more or less tension, as occasion may require.

The upper roller B is supported at one end in the side plate A and at its other end in a bracket B3, so the casings may be inserted at B4 between the rollers B and B and may be removed at the same point whenever4 desired, as will be understood from Figs. 2 and 4 of the drawings. A feed-board B5 leads up to the rollers B and B and supports the casings as they pass to said roller, pins B6, projecting upwardly from the board B5, forming guides for the casings as they pass to the rollers. The rollers B B may be termed the front feed-rollers, and in'rear thereof I provide `a second pairV of feed-rollers OO', constructed and supported similarly to Specification of Letters Patent.

Patented March 5, 1907.

the rollers B B', the lower roller being arranged for adjustment by screws C2 and the upper roller being supported in a bracket O3, so one end of the roller O will be unobstructed, and an inclined feed-board C5, having guidepins C6 leading up to the rollers O and O', as best shown in Fig. 1 of the drawings.

Between the front and rear feed-rollers' I provide a pair of Scrapers, one below the other and preferably nearer the front feedrollers, as shownin Iig. 1. D and the upper scraper E are constructed alike, but are arranged with their blades reversed, so that the lower scraper may properly operate upon the under side of the casings while the upper scraper operates upon the 'upper side of the casings, so that I-secure a pressure upon both sides of the casings. The Scrapers D and E are journaled in the framing and are turned positively by the gearing, presently described, in the directions indicated by the4 arrows in Fig. 1, with their blades D E inclining rearwardly with The lowerscraper respect to the direction of revolution of the scraper. These Scrapers are alike and the description of the scraper D (shown in Fig. 7) will answer for both Scrapers. The scraper D includes a central body or core, made polygonal and preferably octagonal, as shown, and the blades D are secured at their inner ends to the flat faces D2 of the body portion or core, so that the blades project in approximately a tangential direction and incline, as will be understood from the arrows in Fig. 1, rearwardly with respect to the direction of revolution of the scraper, so that the blades will operate with a scraping action against the casings, and these blades being made in the form of open frames and of spring material are resilient, so that I avoid any injury to the casings or tearing thereof by the revolution of the scrapers in the operation of the machine. By making the blades in the form of open frames I not only increase their resilience, but I also provide for the free discharge of water upon the casings and through the blades in the use of the machine, as more fully described hereinafter.

In connection with the Scrapers I provide means for pressing the intestines toward the blades of the pair of Scrapers. This pressing means preferably comprises ay handle-lever IOO j ing-plates d and c, and in this connection itl with a rack F3 on the side plate A and provided below its pivot F with the oppositelyprojecting plates d and e, which are spaced apart at their adjacent ends, where they are secured to the lever F by means of the brackets d and c, so that a way is provided between the adjacent ends of the pressingplates for the passage of the casings in the use of the invention. As these plates d and c project in opposite directions with respect to the pivot F of the presser, it will be noticed that by tilting the presser on its pivot F the plates d and e will be adjusted toward and from their respective scrapers and with uniform pressure, and the detent at F2, which may be of any suitable form of pawl engaging with the rack F3, will hold the device in any desired adjustment. By this means the casing passes through the machine, and being fed by the rollers B B C C it will be scraped on its lower and upper sides by the scrapers D and E operating against the presswill be noticed that the scrapers are provided with resilient blades, and the pressers are practically unyielding, and the regulation of pressure is secured by the adjustment of the pressing devices, as before described.

In the making of large casings it is desirable to turn them inside out, and to this end 'I provide the turning device G in rear of the feed-rollers C and C and also provide above the turning device G a feed-roller H and between said feed-roller and the roller C a guide-rod I and a swinging gate J above the same and adapted to hold the casings when they are being applied to the turning device. The feed-roller ri is provided with a series of plates H, notched in their outer edges at H2 and forming clasps to engage the casings and feed them down to the turning device G.

The turning device G comprises a series of arms G, secured at their lower ends at G2, springing outwardly at their upper ends at G3, together with a compressor by which the ends G3 may be forced toward each other to receive one end of the casing and then be released to spring out within said end and hold it while the casing is being turned inside out in the operation of the machine. The compressor includes a ring K, sliding along outwardly-inclined portions G4 of the arms G, so that when the compressor is in its lower position, as shown in Fig. 6 the arms G should be free to spring outwardly at their upper ends, but may be contracted by the upward movement of the ring K by its lever K', so the upper ends of the arms will be contracted to permit the end of the casing to be slipped readily thereover. In the illustration shown in Fig. 6 the casing is illustrated -in the act of being turned inside out, the

weight of the ca'singaiding such action and a stream of water discharged from the nozzle L facilitating the operation as it is discharged into the pocket formed by the turning of the casing, and thus serves as a feeder as well as a cleansing agent, as will be understood from Fig. 6 of the drawings.

In driving the several parts the upper and lower rollers B B and U C are geared together, as will be understood from Fig. 4. 'Ihe feed-roller His provided with a sprocketwheel l, the lower roller G is provided with a sprocket-wheel 2, the scraper E is provided with a sprocket-wheel 3, the scraper D is provided with a sprocket-wheel 4, and the lower roller B is provided with a sprocket-wheel 5, and the chain 6 is disposed over these sprocketwheels in such manner, as illustrated in Fig. 3, as to drive the said parts in the directions indicated by the arrows in Figs. 1 and 3, motion being given in any suitable manner to any one of the drive-pulleys 1 to`4, as will be understood by those skilled in the art. Ordinarilythis may be effected by means of a band operating upon the pulley 6, as shown in Figs. 3 and 4.

In supplying water to wash the casings at the different stages I employ a main M in the form of a pipe extending alongside the plate A. This main M has upper and lower branches M and M2, being returned at M3 and provided with the inwardly-projecting dischargepipes M4 and M5, discharging through their perforations toward the rollers B and B, the discharge-pipes M and M7 discharging, respectively, to the scrapers D and E, the pipes M8' and M discharging, respectively, to the rollers C and C', and the pipe L2, having the downwardly-directed nozzle L', discharging to the casing as it is being turned inside out. By this construction I am able to keep the feedrollers and scrapers clean and also supply water to wash the casings as they'are passing through the machine.
